Abstract (en)
[origin: EP3197231A1] The present application discloses a method of transmitting and receiving a signal to and from an evolved Node B (eNB) by user equipment in a wireless communication system that supports carrier aggregation. In particular, the method is characterized by including the steps of: performing first carrier detection on a channel that is set for a predetermined frequency region of an unlicensed frequency band; performing second carrier detection on a sub channel when, as a result of the first carrier detection, the channel is in an IDLE state; and performing one of uplink signal transmission or downlink signal reception from the eNB on the sub channel when, as a result of the second carrier detection, the sub channel is in an IDLE state.
